Abstract
A new type of Equisetum arvense aerial part (EAAP) extract was ready to be tested as a corrosion inhibitor for steel-based parts in Multi-stage flash (MSF) segments while the segments were being acid cleaned. The EAAP extract was identified using Fourier-transform infrared (FTIR) and High-performance liquid chromatography (HPLC). When compared to the specimen exposed to blank solution, EAAP extract molecules covered about 97% of the carbon steel surface in 2 M HCl solution, and the corrosion rate was reduced to 0.58 ± 0.02 μg cm−2 h−1 at 300 mg l−1. EAAP extract tends to have a blended impact on both anodic and cathodic sites on the surface of carbon steel. The thermodynamic activation factors are substantially higher in the presence of extract solution than in the absent of extract, demonstrating that the carbon steel surface would corrode slowly in the presence of EAAP extract. Theoretical models were used to validate the adsorption of EAAP extract on steel surfaces.

A new type of Equisetum arvense aerial part (EAAP) extract was ready to be tested as a corrosion inhibitor for steel-based parts in Multi-stage flash (MSF) segments while the segments were being acid cleaned
Kaempferol-3,7-di-O-glucoside, kaempferol-3-O-rutinoside, and isoquercetin were identified as the primary peaks 1, 5, 6, and 9, respectively
As well as quantum chemical findings, indicated that the EAAP extract can be utilized as a corrosion inhibitor for steel-based components in the MSF segments during acid cleaning using a 2 M HCl solution
Summary
A new type of Equisetum arvense aerial part (EAAP) extract was ready to be tested as a corrosion inhibitor for steel-based parts in Multi-stage flash (MSF) segments while the segments were being acid cleaned. Alibakhshi et al.[21] used infrared spectroscopy to examine the molecular structure of Persian liquorice leaves They found that the presence of OH, COOH, and CO functional groups in Persian liquorice leaf extracts may help to prevent corrosion by coordinating with Fe atoms on the steel surface. The present study objective is to generate successful corrosion inhibitors for steel-based materials in the MSF segments that are low in toxicity. Through this view, the Equisetum arvense aerial part (EAAP) extract was explored during acid cleaning as an inhibitor of corrosion of steel-based materials. We employed theoretical concepts to confirm the efficacy of EAAP extract as a corrosion inhibitor
